Once a white supremacist gang member, King was sent to the slammer because she and her hate-spewing pals robbed and pistol-whipped a Jewish adult video shop clerk, she told BBC.

“I had tattoos all over my body. I had Vikings tattooed on my chest, a swastika on my middle finger and ‘Sieg Heil’ on the inside of my bottom lip, which was the Hitler salute,” King said of herself at age 23.

“I joined the [gang] because they accepted my violence and anger without question,” she confessed.

One night in 1998, King and other gang members got drunk at a bar and went on a violent rampage, she said. She beat up a woman in the bathroom — and they sped off to rob the adult video shop, she said.

“We drove around all pumped up and started talking about what a race war would be like in the US,” she said. “We talked about how it was OK to hurt people who aren’t like us and we decided to go and find a place to rob.”

King was later sent to a federal detention center in Miami, where she became unlikely friends with the Jamaican woman, she said.

“I was in the recreation area smoking when a Jamaican woman said to me, ‘Hey, do you know how to play cribbage?’” she said, referring to the card game.

She didn’t. But the woman taught her to play and they eventually become close, breaking through the racial barriers of prison groups. Soon, she was “in” with the Jamaican gals.

When an article about her court case was printed in the local newspaper — threatening to make her a target behind bars — one of the women hid it to protect her, she recalled.

“I hadn’t really known any people of color before, but here were these women who asked me difficult questions but treated me with compassion,” King said.

But later she was moved to a prison in Tallahassee, where a different Jamaican woman immediately began to pick on her, she said.

“People said she had been in violent gangs and was a real badass. One day as I passed, she asked: ‘How do you even get to be like that?’” she said, referring to her former life as a neo-Nazi.

Instead of fighting, “I stopped and answered her as fully and honestly as I could.”

The two women talked and realized they had had similar rough lives on the streets. Over time, they became friends, cellmates — and eventually lovers.

It was the first serious gay relationship either of them had ever had, she said.
